以铵法造纸的纸浆废液为原料，利用固相堵塞、液相驱油的原理，在中原石油勘探局文明寨高含水小断块油田上进行了注入井调剖工艺研究，并已在现场试验了５１井次。结果表明，纸浆废液调剖剂适合文明寨油田次生大孔道调剖。截止１９９５年１２月，平均单井增油３１０ｔ，含水率下降３．６％，动液面下降１２０ｍ，累计增油３２１００ｔ，降低产水量１１３７５０ｍ３。
Ammonia paper pulp waste as raw material, the use of solid-phase plug, the liquid-phase displacement principle, in the Central Plains Petroleum Exploration Wenmingzhai high water cut fault oil field injection well profile control technology research and has been on the scene 51 wells were tested. The results show that the profile control agent for pulp waste water is suitable for the profile control of the secondary channel of Wenmingzhai oil field. As of December 1995, the average single-well oiling increased by 310 tons, the water content decreased by 3.6%, the moving liquid decreased by 120 meters, and the total oil production increased by 32,100 tons to reduce the water production by 113750m3.
